  • The Role of the Calciner in the Extraction of Lithium from ...

    From this plot, it can be seen that the final lithium extraction was much higher for the leaching of β-spodumene than for that of the α-spodumene. These results indicate the relative inertness of α-spodumene or its high resistivity to biodegradation and/or to chemical attack. As a consequence, in the further studies only β-spodumene was used.
